ADOLFHE GALLINANT, OF ROSLYN, NEW YORK.

REGULATOR FOR CONTROLLING THE DESCENT F ELEVATOR-CARS.

SPECIFICATION forming part of Letters Patent No. 287,922, dated November 6, 1883.

Application filed August 16, 1883. (No model.)

To all whom it may concern:

'Be it known that I, ADOLPHEGAL'LINANT, afcitizen of the Republic of France, but for pastnine years a resident of the United States, and now residing at Roslyn, in the county of Queens and State of New York, have invented a new and useful Regulator for Controlling the Descent of VElevatonCars, of which the following is a specieation, referencebeing had to the accompanying drawings and the letters and' figures marked thereon.

My invention relates tota mechanism for controlling the velocity of the descent of elevator-cars; audit consists, essentially, of a fanlike regulator mounted .on a shaft which is geared in train with a drum, over and around which one of the car-supporting ropes is made to pass. t

Prior to my invention it has been customary to provide some mechanical means for stopping the car at once in case of the breaking of the ropes; but this sudden stoppage of the car is decidedly objectionable, in that the mechanism employed for that purpose is subjected to a sudden andviolent strain, and is liable to break and the car fall; but with my improved regulator this obj ection is avoided, .and in case of the breakage of the hoisting-ropes or its operating mechanism the car would drop to the bottom of the hoistway at a safe and easy rate of speed, and all danger of breakage would 'be avoided.

In the accompanying drawings, Figure l is a view, partly in section, of an elevator-car arranged to be operated by my improved hoisting and regulating mechanism.V Fig. 2 is a side view, on an enlarged scale, of the mechanism located at the'topof the hoistway. In this view the side frame has been removed. Fig. 3 is a `plan `view of the same. Fig. 4 is a side View, partly in section, of one arm of my regulator. online x as, Fig. 4, showing theleaves of the fan closed 5 and Fig. 6 is a similar view, show ing the leaves of the fan open.

Similar letters refer to similar parts throughout the several views.

A represents the lioistway in which the car B rides, said car being guided in yany of the well-known ways.

C C are the hoisting or lifting ropes, which Fig. 5 is asectional view taken are secured to cross-head of the car, and pass over the pulleys D and DQand E and E', respectively, and thence down to the drum F, which drum, it will be understood, is so arranged as to be actuated by the power employed for raisingthe car.

The engine or power employed for driving the drum F is controlled, in the ordinary manner, by a rope which is always within reach of l 1 the elevator attendant; but as such controlling mechanism forms no part of my invention, I

have not thought it necessary to illustrate the v I is secured to the cross-head or any other part ofthe car B, which is separate from the other two cables, and from thatpoint the rope passes up and around the pulley H, as described, and thence to and over a pulley, K, and carries a weight, L, on what might be termed its free end. This weightLisnot intendedfor a counter-balance, and simply acts to maintain the frictional contact between the rope I and the drum or pulley H.

YA large gear-wheel, M, which is' carried by the shaft G, meshes with a pinion, a, on a shaft, as N. This shaft N in turn carries a large gear-wheel, O, which meshes with a second. pinion on a shaft, P, upon which shaft there is mounted a fan, asl. This fan B is preferf ably constructed with four arms, as shown in the drawings, although the number of arms may be changed should it be deemed desirable.

Each arm of this fan isA provided with two wings, as b b', which are so hinged or secured to the arms c c that when the elevator-car is descending they will spread out, as shown Ain Fig. 6, and by their impact against the surrounding atmosphere regulate the velocity of -the descent of said car, while when the car is IOO being raised they occupy the position shown in Fig. 5, in which position they offer no resistanee to the raising of the car.

In order to prevent too great a spread of the wings b b', Iattaoh to each- Wing a chain, as d, the other end of which chain is secured to an arm, as T, (see Fig. 6,) and by this ar- Y rangement-Inot only obtain a uniformity of spread, but am enabled to regulate said spread by changing the length of the chains cl.

In order to regulate the effect produced by the revolution of the fan R, I have so arranged the leaves b b that they can be moved upon the arms c cA to or from the shaft I). This adjustment of the arms is accomplished by means of sleeves, as e e, to which the leaves or Wings b b of the fan arehinged, said sleeves being arranged to pass over and be carried by the arms c, to which arms the sleeves e e are secured, in such position as may be desired, by means of the setsorews kIc k.` By this means the descent of the ear is regulated to suoh speed as may be desired.

y I claim as my invention v 1. `The Combination of an ,elevatoncaig a rope or ropes, as c c, for raising and lowering 25 the same, a rope, as I, actuating a set of accelerating gear-Wheels, and a fan provided with folding Wings driven by said gear-wheels, substantially as described, and for the purpose speeiiied. 3o

2. The fan R, actuated by the movement of an elevatonoar, having Wings b'b capable of adjustment upon the arms c c, substantially as and for the purposes herein speeiiied.

3. rlhe fan R, receiving its motion from the 3 5 elevator-ear by means of suitable connections and gearing, said fan being composed of the Wings b b', hinged to sleeves e, which are adjustable upon the arms c, in combination with chains d, connecting said Wings b b to the rigid 4o arm'T, all substantially as and for the purposes herein specified. y

fitness my hand this 13th day of August, 1883.
